*ActionReactionForce()
Creates an action-reaction force.
Syntax
*ActionReactionForce (force_nam e, "force_label", { TRANS ROT TRANS_ROT }, body_1, body_2, point, Optional: ref_marker)
Arguments
- force_name
- The variable name of the action-reaction force.
- force_label
- The descriptive label of the action-reaction force.
- TRANS | ROT | TRANS_ROT
- This argument indicates whether the action-reaction force has translational, rotational, or both translation and rotational components.
- body_1
- The body to which the active force is applied.
- body_2
- The body to which the reactive force is applied.
- point
- The point at which the force is applied.
- ref_marker
- An optional argument for the reference marker in which the components of the force are specified.
Example
*Point(p_jnc_bmp, "Jounce bumper pt")
*Body(b_axle, "Axle", p_axle_cg)
*Body(b_frame, "Frame", p_frame_cg)
*Marker(mrk_ref, "Force reference", b_axle, p_wc)
*ActionReactionForce(frc_bmp, "Jounce bumper force", TRANS, b_axle, b_frame, p_jnc_bmp, mrk_ref)
Context
Properties
Property | Returns Data Type | Description |
---|---|---|
b1 | Body | Body to which the force is applied. |
b2 | Body | Body to which the reactive force is applied. |
b3 | Body | Body to which the reference marker is attached. |
fx fy fz | real or string | A number, MDL expression, or solver expression that determines the value of the translational X, Y, and Z components of the force. |
i | Marker | Marker attached to b1. |
j | Marker | Marker attached to b2. |
jfloat | Marker | Floating marker attached to b2. |
label | string | The descriptive label of the action-reaction force. |
id | long integer | The solver ID of the action-reaction force. |
rm | Marker | The reference marker in which the components of the force are specified. |
state | boolean | Control state (TRUE or FALSE). |
tx, ty, tz | real or string | A number, MDL expression, or solver expression that determines the value of the rotational force about the X, Y, and Z axis. |
varname | string | The variable name of the action-reaction force. |
Comments
*ActionReactionForce() is used to apply action-reaction forces to points on bodies.
If the optional argument for ref_marker is not specified, a global inertial frame is used as the reference marker for specifying force components.
